Hi, I just joined this forum. Hope I write in the right place ;D
I am planning to go with a 1.9aaz from a mk3 in my mk1.
I am aiming for about 180+whp is it possible? Is even more possible? :o
I'm wondering what does the aaz need for that goal and where can I find forged parts for it (cranks, pistons, rods...).
And can the SDI camshaft fit, and will it improve HP like in TDI's?
What is the longest gearbox to fit an aaz?
All the info is useful thanks so much.

Welcome to the forum. I don't do conversions so no help to you on HP, cams, and such. Others here will have to chime in on this one.

180whp is possible, i am not sure that it will live long at that power level, they never seem to.
the key to make power is to keep the engine cool, use a good injection pump, and use a good turbo like he200wg or he221w. idi engines are not forgiving when it comes to heat.
i would recommend you use arp hardware in the bottom end and possibly use the tdi h beam rods, you will have to clearance your intermediate shaft for them to fit
the sdi cam is a bit hard to find, and a mild upgrade, the money is better spent on a dr diesel cam from giles, or a frank06 cam(assuming it will work with an aaz)
for the gearbox any watercooled 4 cylinder vw transission will bolt on. if you stick to an 020 it will bolt straight into your chassis.
